Elbow Pressure Balanced

Style 5100E

General Rubber’s Style 5100E elbow pressure balanced rubber expansion joint is designed to absorb all-directional movement while continuously self-restraining the pressure thrust forces. This arrangement consists of tie devices inter-connecting its main joint section to its opposing balancing joint section and is commonly used when the support structure or adjacent equipment have load limitations. The pair of spool type bodies are constructed with full rubber flanges, high-grade leak-proof tubes, multiple layers of high-strength tire cord, high tensile steel reinforcements, seamless covers and hot dip galvanized steel retaining rings. Additionally, they are designed to reduce noise and vibration, have a cycle life in the tens of millions, compensate for misalignments, provide access to piping and equipment and relieve pipe and anchor stresses. The economic benefits of using pressure balanced designs include a smaller system footprint as well as far fewer guides, anchors and supports.
